Biography

Dr. Pennesi was born in Mount Kisco, New York, and moved to Dallas, Texas at a young age. For college, he moved to the east coast and attended the University of Pennsylvania for his undergraduate studies. There he graduated summa cum laude with a BS in biomedical engineering and was awarded the Herman P. Schwann award in bioengineering for exemplary scholarship.

Dr. Pennesi's interest in degenerative retinal disorders began shortly after his first year in college, when he spent a summer working at the Retina Foundation of the Southwest. He worked under the supervision of Dr. David Birch and saw patients with retinal degenerations such as retinitis pigmentosa as well as studying animal models of this disease.

After college, Dr. Pennesi completed a combined M.D./Ph.D. at Baylor College of Medicine in Houston, Texas. He performed his graduate Ph.D. work in the Department of Neuroscience in the lab of Dr. Samuel Wu. His thesis work focused on identifying new animal models of retinal degeneration. He received numerous awards while in graduate school, including the John J. Trentin Award for earning the highest GPA in his class and the BRASS scholarship for playing an active role in community service.

For his residency training, Dr. Pennesi spent his internship year in San Diego at Scripps Mercy Hospital, followed by his ophthalmology residency at the University of California, San Francisco. During residency he was awarded the Hogan/Garcia award for the best resident research project. After residency he completed an ophthalmic genetics fellowship under the tutelage of Dr. Richard Weleber.

Dr. Pennesi joined the faculty of Casey Eye Institute and is now an Associate Professor in Ophthalmic Genetics and as the chief of the Ophthalmic Genetics Division.

Both Research to Prevent Blindness and the Foundation Fighting Blindness have recognized Dr. Pennesi with career development awards to support his ambition to conduct transitional research that will bring treatments for diseases such as retinitis pigmentosa from the laboratory to the clinic. Additionally, he is the recipient of the 2011 ARVO/Alcon Early Clinician Scientist, the Alcon Young investigator Award in 2014, and the Casey Eye Institute Resident teach award. His research focuses on developing novel treatments for inherited retinal diseases. He is currently exploring the potential of a new class of drugs to up regulate protective growth factors in the retina.
